The screen is intentionally simple. This is the right place for local-first
copy, future AI-sharing controls, and developer/founder-mode toggles.
LLM connection controls live in `presentation/settings_view.dart` and persist
through `core/llm/llm_config.dart`. Provider-specific model discovery and debug
prompt calls are owned by `core/llm/llm_service.dart`.
